Tripp Lite 550VA 300W Compact UPS 8-Outlets INTERNET550SER

Compact Desktop Battery Backup

The Tripp Lite INTERNET550SER is a 550VA 300W uninterruptible power supply designed for desktop workstations and networking gear. It delivers battery runtime during outages so connected devices can be shut down safely. The unit suits home offices or small business desks where brief power loss risks data corruption. Its 6.25 kilogram weight allows stable placement on a shelf or floor.

Eight Protected Outlets and Data Ports

Eight NEMA 5-15R receptacles provide surge protection for all connected equipment, with four outlets supplying battery backup power. DB9 and RJ11 ports extend suppression to serial and telephone lines, reducing damage risk from line transients. The 120V 50/60Hz input plugs directly into a standard wall socket without special wiring. A compact footprint keeps cable routing tidy in tight spaces.

Replaces Basic Surge Strips for Critical Loads

This UPS upgrades a plain power strip by adding 3.5 minutes of runtime at full 300W load, bridging short utility interruptions. It protects routers, modems and a single workstation from voltage sags and spikes that a strip cannot stop. The jump is worthwhile when an unexpected shutdown would lose unsaved work or drop a network link. It does not support high-wattage gaming rigs or multi-monitor arrays that exceed the 300W rating.
